Get Multiple Connection Strings in appsettings.json without EF

Question

Just starting playing with the .Net Core RC2 by migrating a current MVC .Net app I developed. It looks like to me because of the way that configuration is handled with apps

Answer 1

You can use Options to access in DAL layer. I will try to write simple example(RC1):

First you need to create appsettings.json file with below content:

{
    "ConnectionStrings": {
      "DefaultConnectionString": "Default",
      "CustomConnectionString": "Custom"
    }
}

Then create a class:

public class ConnectionStrings
{
    public string DefaultConnectionString { get; set; }

    public string CustomConnectionString { get; set; }
}

And in Startup.cs

    private IConfiguration Configuration;
    public Startup(IApplicationEnvironment app)
    {
        var builder = new ConfigurationBuilder()
           .SetBasePath(app.ApplicationBasePath)
           .AddJsonFile("appsettings.json");

        Configuration = builder.Build();
    }
    public void ConfigureServices(IServiceCollection services)
    {
        // ....
        services.AddOptions();
        services.Configure(Configuration.GetSection("ConnectionStrings"));
    }

Finally inject it in the DAL class:

    private IOptions _connectionStrings;
    public DalClass(IOptions connectionStrings)
    {
        _connectionStrings = connectionStrings;
    }
    //use it
